Specification of Letters Patent.

Patented June 6, 1911.

Application filed. April 6, 1910. Serial No. 553,712.

To all whom it may concern:

Be it known that I, Gnonen L. GODFREY, a citizen of the United States,and a resident of Steuben, in the county of \Vashington and State ofMaine, have invented a new and Improved Automatic VVeather- Strip, ofwhich the following is a full, clear, and exact description.

An object of the invention is to provide a weather strip for use onclosures such as doors and the like, to prevent any moisture orinclement weather from getting into a room through the space ordinarilyfound between a closure and the casing thereof. For the purposementioned, use is made of a casing provided with means engaging a secondcasin in connection with a packing, and spring-controlled means forautomatically raising or lowering the packing when the door is opened orclosed.

Reference is to be had to the accompan ing drawings forming a part ofthis specification, in which similar characters of reference denotecorresponding parts in all the views, and in which- Figure 1 is a sideelevation of a portion of a door equipped with my device, parts beingbroken away to disclose the underlying structure; Fig. 2 is a partialsectional side view of the same, showing my device in its normalposition; Fig. 3 is a partial sectional side view showing my device withthe pack- 111g raised from the sill or casing, and Fig. 4 is a sectionalend view taken on the line 4-4 in Fig. 2.

Referring more particularly to the views, I employ a door 10, hinged at1.0 and having a groove 11, extending the width of the door in the underside of the same. In the groove 11 is disposed a casing 12, open at thebottom and having its edges 13 turned upwardly to form guides, as willbe easily seen by referring to Fig. 4, and inside the casing 12 is asecond casing 14, adapted to slide in the guides formed by the edges 13.A third casing 15, having secured thereto a packing 16, is provided, andextending transversely through the casing 15 are pins 17, adapted toslide in angular slots 18, formed in the sides of the casing 14. An endplate 19, is secured at one end of the door, and the casing 14 isadapted to abut thereon, and on the other end of the door a plate 20 issecured, and the other end of the casing 14 is adapted to abut thereonwhen the packing is raised from the sill. 21 of the door 10.

In a chamber 22, over the groove 11, is mounted on the casing 12 a frame23, provided with a spiral spring 24, the end 26 of the frame 23 beingrigidly secured to the casing 12, while the end 27 is adapted to slidein the frame 10 and is secured to the casing 14 by means of a lug 28,held in a block 29, adapted to slide in the groove 11. A plug 30provided with a grooved end 31 is screw-threadedly secured to the block29 so that the plug can be conveniently adjusted relative to the block29.

In the operation of my device, when the door 10 is closed, the plug 30is pressed inwardly against the pressure of the spring 24, and holds thecasing 14 against the plate 19, thus securing the casing 15 in itslowest position and engaging the packing 16 with the door sill 21. henthe door is opened, the plug 30 springs outwardly, being actuated by thespring 24, which pulls the casing 14 toward the plate 20, thus forcingthe pivots 17 to slide upwardly in the slots 18, thereby carrying thecasing 15 upwardly and causing the packing 16 to disappear inside thegroove 11, as shown most conven iently in Fig. 3. When the door is againclosed, the plug 30, coming into engagement with the door casing 32, ispushed inwardly and the packing 16 is again forced downwardly to engagethe door sill 21.

In placing the spring in my device at the hinged end. of the door,several important advantages are apparent, which would not appear if thespring were disposed at the other end of the door. Should it be desiredat any time to shorten the width of the door, this can easily beaccomplished without in any manner destroying the operative parts of myweather strip, and by disposing the spring 24 over the casingsdescribed, the direct strain on the spring is substantially decreased.Furthermore. by placing the spring at the hinged end of the door, thejar or vibration caused when the spring is operated, is greatly lessenedby having the spring near the fulcrum of the door.

Although I have shown a particular construction for the purpose ofdescribing my invention, it will be understood that the scope of thesame is fully disclosed in the appended claims.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. A Weather strip comprising a fixed casing having its edges turned toform a horizontal track, a second casing contained Within the fixedcasing and mounted to move on the track, actuating means forming part ofthe second casing for operating the same and a packing mounted on thesecond casing and adapted to slide therein.

2. A Weather strip comprising a fixed casing, a 1ongitudina1ly-extendingtrack thereon, a second casing contained in the fixed casing and mountedto move on the track, a third casing contained in the second cas- 15 ingand mounted to move angularly thereon a packing in the third casing, andmeans on the second casing for operating the same to move the thirdcasing.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing Witnesses.
